lNlPROVEMENT IN WlNDMlLLS.

Specification forming part of Letters Patent No. 18 l, 174, dated August 15, 1876; application filed J nne 7, 1876. l

To all whom it may concern Be it known that I, ARTHUR HUMPHREY,

of Arcola, in the county ofDouglas, and in the State ofIllinois, haveinvented certain new and useful Improvements in Windmills; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked there- 'on, making a part ofthis specification.

Figure 1 is a side elevation of my windmill. Fig. 2 is a front view of the wheel. Fig. 3 is a perspective view of the mill.

A represents the usual center tower. B is the turn-table, placed on the upper end of the center tower A, and having the rudder O bolted permanently thereto. A suitable distance below the turntable, on the tower A, is a ring, D, connected with-the turn-table by an arm or brace, E. G represents the wheel, provided with a hollow conical hub, H, projecting forward in front of the wheel, and attached to the front end of a' center shaft,- b, that has its bearings in the upper end of the wheelstatf I, and in an arm, reprojecting therefrom, said arm extending into the hollow conical hub, as shown in Fig. 3. By this construction the weight of the wheel is directly between the two bearings, whereby only short boxes for the journals need to be used, and consequently there is but little friction. The wheel staif or support Iis, near its upper end,

provided with a half-hinge, which connects with a similar half-hinge on the turn-table B, as shown at d,'while the lower end of said staff or support is, by a hinge at 01, connected with the ring D on the center tower. By means. of these hinges the wheel is enabled to turn almost square around, thus giving the governor complete control over its motions. It will be seen that by this construction of at right angles with the rudder G, in one or more boxes on or under the turn-table B. At

one end of this shaft is suspended the governor fan or vane J, and at the other end is a crank, 0, connected to the wheel-staff I by a rod, h. When the wind blows hard enough it carries the fan or vane J back until it is in a horizontal position. In turning, the fan, by its comfections, :urns the wheel on its hinges until it is parallel with the rudder. When the wind slacks, the weight offrhe fan turns the wheel back at right angles with the rudder, the governor fan or vane thus serving the purpose of a weight and fan.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The wind-wheel G, provided with the hollow conical hub H, in combination with the shaft 1), staif I, and arm (1., arranged so that the wheel will be between the two bearings, as and for the purposes herein set. forth.

2. Awind-wheel secured to a shaft having its bearings in a staff or support hinged to the turn-table, substantially as andfon the purposes herein set forth.

3. The combination of the turn-table B with rudder 0, ring D, brace E, hinged staff or support I, with arm a, shaft 1), and wheel Gr,

with hollow conical hub H, all constructed substantially as and for the purposes herein set forth.

4. The combination of'the suspended fan J, shaft f, with crank c, connecting-rod h, and hinged stafl' or support I, carrying the wheel G H, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 29th dayof November, 1875.

ARTH R HUMPHREY.
